preparation example Construction

[0020] A preparation method for metal and non-metal surface degreasing agent, comprising the following steps:

[0021] 1) Add surfactant into the reaction kettle, then add 30% sodium hydroxide aqueous solution with stirring, and adjust the pH value to 7;

[0022] 2) Add appropriate amount of water to another container, then add sodium chloride, stir to dissolve completely;

[0023] 3) Add emulsifier into another reaction kettle, start stirring, add appropriate amount of water, then add penetrant, stir to dissolve completely;

[0024] 4) Mix the materials obtained in step 1, step 2 and step 3, add water to the full amount, stir evenly, and the product is ready.

[0025] In following embodiment, emulsifying agent can be any one in emulsifying agent OP-15, emulsifying agent OP-20, emulsifying agent OP-30 and emulsifying agent OP-40; Surfactant agent can be dodecylbenzene sulfonic acid or stearic acid. The penetrant can be any one of penetrant JFC, penetrant JFC-1, penetrant JF...
